A below-knee prosthesis with a pin lock system is a common type of prosthetic limb designed for individuals with a transtibial amputation (amputation below the knee). Here's a breakdown of what it is and how it works: 🔧 What is a Pin Lock System? The pin lock system is a mechanical suspension system used to keep the prosthesis securely attached to the residual limb. ✅ Components: Silicone liner with a pin – The amputee wears a soft, gel-like liner over the residual limb. A metal pin is attached to the bottom of this liner. Socket – This is the hard shell custom-molded to the amputee’s limb. Locking mechanism – Built into the bottom of the socket, it engages the pin when the prosthesis is donned. 🛠️ How it works: The user inserts the residual limb with the liner into the socket. The pin slides into the locking mechanism and "clicks" in place. To remove the prosthesis, the user presses a release button near the bottom of the socket to disengage the lock. 🧍‍♂️ Advantages: Secure fit – Reduces pistoning (up and down movement). Easy to use – The click mechanism gives confirmation it's locked. Comfortable liner – Provides cushioning and skin protection. # evolution healthcare pvt ltd #artificial limb#AFO #KAFO # #foot drop splint #insole forheel pain , flat foott#
